Download or read book Predicting the Effects of Ocean Warming on the Global Distribution of Sea Lice, Lepeophtheirus Salmonis and Caligus Elongatus written by Victoria Ngoc Phuong Lai and published by . This book was released on 2020 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea lice are marine ectoparasitic copepods. Commonly found in European and North American waters, these species have caused extensive ecological and economic damage in salmonid aquaculture. The significant impacts of sea lice in farm and wild fish populations has been the key drivers in the rising number of studies on sea lice infestations. While the effects of various environmental factors on the local dispersion patterns and transmission dynamics of sea lice have been observed, the lack of studies on the global sea lice niche have limited our understanding of the effects of climate warming on their distribution and ecology. Building on the existing knowledge of sea lice ecology, response to temperature changes, and their relationships with their fish hosts, I predicted the niche of two sea lice species, Lepeophtheirus salmonis and Caligus elongatus. The MaxEnt models predicted a contraction in the L. salmonis niche range from the past (“Last Glacial Maximum” 22,000 years ago) to the present, but an expansion from the present to the future (year 2100). Distance from land and SST were the primary variables regulating the distribution of L. salmonis. For C. elongatus, the models predicted an expansion from the past to the present, but a contraction from the present to the future. Depth and SST were the primary variable regulating the distribution of C. elongatus. A consequence of these changes on salmon farm management is that farms may become more likely to experience sea lice infestation in the future, particularly by L. salmonis, which may lead to additional ecological and economic impacts in the future. However, additional research is necessary to examine the long-term effects of climate change on the host-parasite system between salmonids and sea lice.

Available in PDF, EPUB and Kindle. Book excerpt: North America contains an incredibly diverse array of naturalenvironments, each supporting unique systems of plant and animallife. These systems, the largest of which are biomes, formintricate webs of life that have taken millennia to evolve. Thisrichly illustrated book introduces readers to this extraordinaryarray of natural communities and their subtle biological andgeological interactions. Completely revised and updated throughout, the second edition ofthis successful text takes a qualitative, intuitive approach to thesubject, beginning with an overview of essential ecological termsand concepts, such as competitive exclusion, taxa, niches, andsuccession. It then goes on to describe the major biomes andcommunities that characterize the rich biota of the continent,starting with the Tundra and continuing with Boreal Forest,Deciduous Forest, Grasslands, Deserts, Montane Forests, andTemperature Rain Forest, among others. Coastal environments,including the Laguna Madre, seagrasses, Chesapeake Bay, and barrierislands appear in a new chapter. Additionally, the book covers manyunique features such as pitcher plant bogs, muskeg, the polar icecap, the cloud forests of Mexico, and the LaBrea tar pits.“Infoboxes” have been added; these include biographiesof historical figures who provided significant contributions to thedevelopment of ecology, unique circumstances such as frogs andinsects that survive freezing, and conservation issues such asthose concerning puffins and island foxes. Throughout the text,ecological concepts are worked into the text; these includebiogeography, competitive exclusion, succession, soil formation,and the mechanics of natural selection. Ecology of North America 2e is an ideal first text forstudents interested in natural resources, environmental science,and biology, and it is a useful and attractive addition to thelibrary of anyone interested in understanding and protecting thenatural environment.

Download or read book Sea Lice Biology and Control written by Jim Treasurer and published by 5m Books Ltd. This book was released on 2022-10-31 with total page 857 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea lice are one of the most important and costly health issues for Atlantic salmon aquaculture and for culture of many other marine fish species. In addition, the extent and causes of impacts of sea lice upon wild salmonids has proven a hotly debated issue and one that continues to affect public perceptions of aquaculture. It is 29 years since the last dedicated book on sea lice biology and management, Pathogens of Wild and Farmed Fish: Sea Lice (Boxshall and Defaye, 1993), and a volume of current perspectives is overdue. The current book updates knowledge concerning the biology and management of sea lice, authored by over 60 world-leading researchers, practitioners and industry experts, written in an accessible and engaging style. New topics include genomics, vaccinology, physiology and epidemiology, and aspects of interactions with wild fisheries are thoroughly reviewed. Sea Lice Biology and Control is of interest to and provides an invaluable reference for sea lice researchers, parasitologists, students, fish farmers, veterinarians and other fish health professionals, wild fish biologists and managers, regulators, government, fish certification professionals and NGOs. The book provides an authoritative overview of sea lice and their interactions and gives a clear illustration of the application of the principles of integrated pest management in an aquaculture context. 5m Books

This book was released on 2019-06-07 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A remarkable accomplishment.... [This volume] has been and will continue to be a major force advancing freshwater fish parasitology."—Ernest H. Williams Jr., from the ForewordThis thoroughly revised and updated edition of a classic reference work is the definitive guide to the identification of the parasites of freshwater fishes of North America. The book provides information on public health concerns about fish parasites, the methods used to examine fish for parasites, and those parasites found only in very selective organs or tissues. It lists the known species of each genus, along with reference citations that enable readers to find literature pertinent to species identification, life cycles, and in some cases, control. In the heart of the book, each chapter opens with a description of a phylum and its relevant families and genera, followed by a species list for those genera. Drawings illustrate a representative of each genus, and are supplemented by photographic examples.Many new parasites of North American freshwater fishes have been discovered since the publication of the first edition thirty years ago. For this new edition, the author has added new species accounts and revised the taxonomy, expanded descriptions and discussion of the most important fish parasites, provided a glossary to aid nonspecialists, and updated the reference list through 1992. The volume features twice as many illustrations as the first edition, including the addition of 33 color photographs.

Available in PDF, EPUB and Kindle. Book excerpt: The North American freshwater fish fauna is the most diverse and thoroughly researched temperate fish fauna in the world. Ecology of North American Freshwater Fishes is the only textbook to provide advanced undergraduate and graduate students and researchers with an up-to-date and integrated view of the ecological and evolutionary concepts, principles, and processes involved in the formation and maintenance of this fauna. Ecology of North American Freshwater Fishes provides readers with a broad understanding of why specific species and assemblages occur in particular places. Additionally, the text explores how individuals and species interact with each other and with their environments, how such interactions have been altered by anthropogenic impacts, and the relative success of efforts to restore damaged ecosystems. This book is designed for use in courses related to aquatic and fish ecology, fish biology, ichthyology, and related advanced ecology and conservation courses, and is divided into five sections for ease of use. Chapter summaries, supplemental reading lists, online sources, extensive figures, and color photography are included to guide readers through the material and facilitate student learning. Part 1: Faunal origins, evolution, and diversity Presents a broad pictureÑboth spatially and temporallyÑof the derivation of the fauna, including global and regional geological and climatological processes and their effects on North American fishes. Part 2: Formation, maintenance, and persistence of local populations and assemblages Focuses on how local fish populations and assemblages are formed and how they persist, or not, through time. Part 3: Form and function Deals with the relationship of body form and life history patterns as they are related to ecological functions. Part 4: Interactions among individuals and species Discusses the numerous interactions among individuals and species through communication, competition, predation, mutualism, and facilitation. Part 5: Issues in conservation Focuses on several primary conservation issues such as flow alterations and the increasing biotic homogenization of faunas.

This book was released on 2002-04-04 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first volume to thoroughly address health concerns in the aquaculture industry Aquaculture-farming aquatic plants and organisms-is one of the fastest growing sectors of agriculture, yet attention to aquaculture health concerns has not been equal to the rate of the industry's expansion. Public, Animal, and Environmental Aquaculture Health Issues serves as a valuable guide to new enterprises, regulatory agencies, and government agencies that are concerned with safe, controlled aquaculture development. The majority of aquaculture products pose no significant health risk; however, like traditional farming operations, aquaculture has associated risks to employees, animals, the environment, and the consumer. This book addresses potential unanticipated risks from the perspectives of both industrialized and nonindustrialized countries, as well as how to mitigate these risks. Chapters include: * Status of World Fisheries and the Role of Aquaculture * Aquaculture Associated Public, Animal, and Environmental Health Issues in Nonindustrialized and Industrialized Countries * Hazard Analysis Critical Control Point and Aquaculture * Aquaculture and International Trade Regulations * Future Considerations of Global Aquaculture Aquaculture business owners, managers, producers, manufacturers, research and academic scientists, government officials, consultants, and food safety specialists will find Public, Animal, and Environmental Aquaculture Health Issues to be a valuable addition to their professional libraries.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, species and ecosystems have been threatened by many anthropogenic factors manifested in local and global declines of populations and species. Although we consider conservation medicine an emerging field, the concept is the result of the long evolution of transdisciplinary thinking within the health and ecological sciences and the better understanding of the complexity within these various fields of knowledge. Conservation medicine was born from the cross fertilization of ideas generated by this new transdisciplinary design. It examines the links among changes in climate, habitat quality, and land use; emergence and re-emergence of infectious agents, parasites and environmental contaminants; and maintenance of biodiversity and ecosystem functions as they sustain the health of plant and animal communities including humans. During the past ten years, new tools and institutional initiatives for assessing and monitoring ecological health concerns have emerged: landscape epidemiology, disease ecological modeling and web-based analytics. New types of integrated ecological health assessment are being deployed; these efforts incorporate environmental indicator studies with specific biomedical diagnostic tools. Other innovations include the development of non-invasive physiological and behavioral monitoring techniques; the adaptation of modern molecular biological and biomedical techniques; the design of population level disease monitoring strategies; the creation of ecosystem-based health and sentinel species surveillance approaches; and the adaptation of health monitoring systems for appropriate developing country situations. New Directions of Conservation Medicine: Applied Cases of Ecological Health addresses these issues with relevant case studies and detailed applied examples. New Directions of Conservation Medicine challenges the notion that human health is an isolated concern removed from the bounds of ecology and species interactions. Human health, animal health, and ecosystem health are moving closer together and at some point, it will be inconceivable that there was ever a clear division.

Download or read book Coastal Environments in the West of Ireland written by John B. Roney and published by Cambridge Scholars Publishing. This book was released on 2022-11-16 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multi-authored study explores how the natural sciences and the humanities together can understand the connections between the natural environment, the built environment, and the cultural heritage of communities along the west coast of Ireland. Knowledge of the sea and marine life, and what they mean to humanity is dependent on both scientific study and local knowledge, which, in turn, can lead to a greater commitment to sustainability. Until the 1950s, there was little government support for scientific research, nor an interest in helping fisheries beyond near shore catch. Irish fisheries remained small, underfunded, and had difficulty accessing international markets. However, as this book shows, Ireland’s cultural heritage demonstrates a deep appreciation for the coastal environment and a sense of place. This is preserved in the Irish language, in poetry, story and music, and in the ways the Irish lived with an often-wild coastal topography.

Book excerpt: There are currently 3-5 million cases of leishmaniasis in the world and the prevalence is rising. The first chapter in this volume reviews the cell biology of the parasite and its transmission and survival. The second review addresses the apicomplexan protozoan parasites Theileria anulaga, T. parva and T. sergenti which globally cost agriculture over one billion US dollars annually. Current research in this area aims to produce effective, stable and cheap subunit viruses requiring only a single application and the authors predict that success will eventually be achieved with 'naked DNA' vaccines containing cytokine genes as immunopotentiators. The next review is the first in over 30 years to discuss the larva of the class Monogenea.The authors cover morphology, behaviour and structure of many examples providing a detailed reference for researchers. The penultimate chapter discusses the distribution of Schistosoma bovis and considers the reported interactions occurring between parasites and snails. The final chapter reviews one of the most serious parasitic diseases in salmonid aquaculture - sealice. In 1998 the costs due to sealice damage in Scotland alone were estimated at 15-30 million pounds. Discussion of biology and control of these ectoparasites emphasizes the need to understand the basic biology of the parasite. This volume will be essential reading for parasitologists in many branches of the subject.

Download or read book Salmon Lice written by Simon Jones and published by John Wiley & Sons. This book was released on 2011-08-02 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: The salmon louse Lepeophtheirus salmonis is adapted to survive in hostile marine environments of the northern hemisphere, including an ability to parasitize several species of salmon. Salmonids are some of the most economically important and sought after fish for human consumption, and louse parasitism has a significant impact both on cultured and wild fish populations. Salmon Lice is a timely collection of the latest research on the cause and spread of lice infestations and management techniques being designed and implemented to combat this issue. Salmon Lice provides a thorough single volume review of Lepeophtheirus salmonis, the key parasite standing in the way of sustainable and profitable production of salmonid fishes including salmon, trout and charr. Opening with a review of the biology, morphology, life cycle, and larval behavior of the parasite, Salmon Lice proceeds to review the distribution of planktonic larvae of salmon lice, addresses management techniques used in salmonid aquaculture and capture fisheries, provides a practical assessment of the salmon lice issue and explores potential solutions to the problem. With comprehensive coverage of the biology and distribution of this harmful and ubiquitous parasite, Salmon Lice will be of value to fish health researchers, aquaculture and fisheries professionals, and seafood industry personnel to inform the management of both cultured and wild salmonid populations. Key Features: In-depth coverage of a key parasite impacting viability and sustainability of salmonid fisheries and aquaculture Integrates parasite biology and hydrodynamic models in diverse coastal ecosystems Provides a practical assessment of the salmon louse issue Reviews international salmon louse monitoring and management techniques used in salmonid fisheries and aquaculture
